The Hollands Creek Demonstration Reach is nestled within the Tatong Valley in North East Victoria. The Demonstration Reach concept was established under the Murray-Darling Basin Authority’s Native Fish Strategy program 2003-2013. The aim of the Demonstration Reach program is to improve these native fish populations using multiple river rehabilitation actions.

Hollands Creek fish community
Hollands Creek is home to the nationally endangered Macquarie Perch (Macquaria australasica), a large-bodied native fish historically widespread throughout Victoria. However, their distribution and abundance have severely declined over the last century and only a handful of populations remain in Victoria. Other large-bodied native fish species in Hollands Creek include Two-spined blackfish (Gadopsis bispinosis) and River blackfish (Gadopsis marmoratus).

Hollands Creek and rehabilitation for fish
In Hollands Creek, multiple river rehabilitation actions have been applied to address the threats to river health and improve native fish populations in the creek. Local, state and federal government agencies along with community groups have invested in a works and community education program to increase native fish numbers and build knowledge. The works program has provided additional habitat for native fish in the form of logs (snags) and rocks, removed riverbank weeds, managed stock access to the creek, improved creek connectivity, provided refuge from low flows, planted riparian vegetation and stocked the reach with native fish.

Rehabilitation works undertaken in Hollands Creek (2008-2014):

  • 126 habitat snags inserted
  • 19 large rocks inserted
  • 29 km of willows removed
  • 24 km of fencing installed
  • Installed a rock-bar (low flow refuge)
  • Rock-bar constructed (low flow refuge)
  • 3,200 Shrubs planted along creek bank
  • Re-stocking 300 Macquarie perch fingerlings into the creek (2010)

Is it working?
Annual electrofishing surveys have been undertaken in Hollands and Ryans creeks since 2008 to monitor the response of native fish species to rehabilitation efforts in Hollands Creek. Results in Hollands Creek have been astounding, with a 1200% increase in the Macquarie perch population, a 1500% increase in the Two-spined blackfish population, and a 400% increase in the River blackfish population over the life of the program. In addition to the increases in abundance, populations of Macquarie perch and Two-spine blackfish have also been strengthened by increases in distribution and size classes, indicating improvements in natural recruitment.

Program partners and support groups
Partnering with relevant stakeholders was essential to foster ownership of the project, effectively improve creek health and demonstrate the value of collaboration. A Community Reference Group included landholders, representatives from local clubs (including Landcare groups and a fishing club) and government agencies. Regular engagement events were held, including on-site meetings and field days with local school students and program partners and through annual fish survey demonstrations. Information signs were installed and project updates were communicated during meetings, in distributed reports, through Demonstration Reach agency webpages, in local media and at research conferences.

Project partners and support groups include;

  • Murray-Darling Basin Authority (MDBA)
  • Department of Environment and Primary Industries (DEPI)
  • DEPI Arthur Rylah Institute
  • DEPI Fisheries Victoria
  • Goulburn Broken Catchment Management Authority (GBCMA)
  • Rural City of Benalla
  • Tatong-Mollyulah Landcare Group
  • And the many landowners and interested community members who participated in field work, provided assistance with river access and advice, supported rehabilitation actions on their properties, and continue to advocate for a healthy Hollands Creek.
